Python Keywords

Keywords in Python are reserved words that have special meanings and serve specific purposes in the language syntax. Python keywords cannot be used as the names of variables, functions, and classes or any other identifier.

Getting List of all Python keywords

We can also get all the keyword names using the below code.

import keyword

# printing all keywords at once using "kwlist()"
print("The list of keywords is : ")
print(keyword.kwlist)

Output:

The list of keywords are: 
['False', 'None', 'True',"__peg_parser__ 'and', 'as', 'assert', 'async', 'await', 'break',
'class', 'continue', 'def', 'del', 'elif', 'else', 'except', 'finally', 'for', 'from', 'global', 'if',
'import', 'in', 'is', 'lambda', 'nonlocal', 'not', 'or', 'pass', 'raise', 'return', 'try', 'while', 'with', 'yield']

How to Identify Python Keywords ?

• With Syntax Highlighting - Most of IDEs provide syntax-highlight feature. You can see Keywords appearing in different color or style.
• Look for SyntaxError - This error will encounter if you have used any keyword incorrectly. Note that keywords can not be used as identifiers (variable or a function name).

Let's categorize all keywords based on context for a more clear understanding.
